in this lesson you will learn the following :
- for loop.
- while loop.
- do while loop.
The code inside the video :
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>LoopingPage</title>
<script>
function ForLoop() {
for (var i = 10; i > 0; i = i - 2) {
//my code
document.writeln("<h1> i = " + i + "</h1> ");
if (i == 5) {
break;
// continue;
}
}
}
function WhileLoop() {
var i = 1;
while (i <= 10) {
document.writeln("<h1> i = " + i + "</h1> ");
i++;
}
}
function DoWhile() {
var i = 11;
do {
document.writeln("<h1> i = " + i + "</h1> ");
i++;
} while (i <= 10);
}
</script>
</head>
<body>
<input type="button" value="while loop" onclick="ForLoop()" />
<input type="button" value="while loop" onclick="WhileLoop()" />
<input type="button" value="Do While" onclick="DoWhile()" />
</body>
</html>
<html xmlns="http://www.w3.org/1999/xhtml">

function ForLoop() {
for (var i = 10; i > 0; i = i - 2) {
//my code
document.writeln("<h1> i = " + i + "</h1> ");
if (i == 5) {
break;
// continue;
}
}
}
function WhileLoop() {
var i = 1;
while (i <= 10) {
document.writeln("<h1> i = " + i + "</h1> ");
i++;
}
}
function DoWhile() {
var i = 11;
do {
document.writeln("<h1> i = " + i + "</h1> ");
i++;
} while (i <= 10);
}
</script>
</head>
<body>
<input type="button" value="while loop" onclick="ForLoop()" />
<input type="button" value="while loop" onclick="WhileLoop()" />
<input type="button" value="Do While" onclick="DoWhile()" />
</body>
</html>
questions :
1- what is the different between while loop and do while loop ?
2- write a loop that print numbers from 20 to 40 but if the number apply devided on 5 print "Boom" instead the number :) ?
